Creating a Terrain

Hello, I just started unity today, and for some reason, when i opened a new project with terrain assets, i cannot create a terrain to play with.

I searched in the unity manual :
“you can add a terrain object to your scene by selecting GameObject > Create General > Terrain from the menu‏.”

however, the create general was not on the list and hence terrain.

Looks like you are using Unity 4.6.

It is now present under:

GameObject → 3D Object → Terrain
